Software Stocks Rally 21% in May: AI Agents Are Sorting Winners From Losers

Enterprise software stocks rebounded sharply in May after a dramatic February selloff, with the iShares Expanded Tech-Software ETF (IGV) climbing 21%—its best monthly performance since October 2001. The rally followed a panic-driven drop in early February, when traders coined ‘SaaSpocalypse’ after $285 billion in market value evaporated, fueled by concerns that AI agents like Anthropic’s Claude Cowork would reduce demand for traditional seat-based software licenses. Analysts had predicted the end of the per-seat pricing model, but three months later, the sector’s recovery suggests investors are re-evaluating which companies will thrive in an AI-driven enterprise environment. The selloff in February was driven by panic rather than fundamentals, with no recession, earnings downturn, or central bank tightening materializing. Heavy call options activity in late May—five times the 30-day average—signaled strong bullish sentiment, though the rally’s sustainability remains uncertain. Snowflake’s May 27 earnings report provided the catalyst, with revenue hitting $1.39 billion (up 34% year-over-year) and product revenue at $1.33 billion, both exceeding expectations. The company also raised full-year product revenue guidance to $5.84 billion and announced a $6 billion AWS partnership for AI infrastructure, alongside the acquisition of Natoma, a startup specializing in enterprise governance for AI agents. Snowflake’s performance reshaped the narrative, positioning itself as a key player in an AI-driven future rather than a casualty. The company framed its role as essential infrastructure for autonomous agents, arguing that AI systems will need platforms to store data and manage access—making Snowflake a beneficiary rather than a victim of AI disruption. While the thesis is compelling, adoption of Natoma’s Model Context Protocol gateway remains limited, with only a few enterprises deploying it as of the acquisition announcement. Most Fortune 500 IT departments are still early in integrating agentic workloads, leaving the long-term impact of AI on software demand unproven. The broader sector’s recovery hinges on whether investors believe AI will replace or expand demand for enterprise software. Snowflake’s strategy—partnering with AWS and acquiring governance tools—suggests it is betting on the latter, while other companies may face pressure if their products become obsolete. The 35% rebound in IGV from its April low reflects cautious optimism, but the market’s focus remains narrow: identifying which firms will dominate the AI-driven enterprise ecosystem. Without broader adoption of agentic technologies, the rally could stall, leaving the sector’s future uncertain.
